Customized Rivet Driver For Ifr Light Modification

Abstract: The In-Flight Refueling (IFR) Light is to be installed on the airframe of the Aircraft and its function is that it is switched on whenever In-flight refueling is in progress. The IFR Light is attached to the airframe with the help of rivets which are permanent fasteners. The position of the IFR Light is extremely intricate and not having adequate space for the rivet driver. Previously, the standard rivet drivers were used for the riveting operation. But due to intricacy & space constraint, there was inadequate space for holding the rivet drivers as required. This led to the deformation of rivet head and improper formation of buib. In such circumstances, it was required to then de-rivet the improper rivets and rivet new ones. In this invention, a Z-shaped rivet driver as shown in Figure 2 was fabricated considering the space constraint. With the help, of th:s ..Net driver, it was possible to gain proper access to the area where the IFR Light:.is.to. be installed. Also, it was also ensured that the problems in the prior method such as deformation of river head and improper formation of rivet bulb were avoided. Also, the need for de-riveting the improper rivets was also avoided.

Specification

1.Title of the invention
Customized rivet driver for IFR light modification.
2.Field of invention
This invention is related to the manufacturing, repair and quality assurance of IFR light. The method relates to the use of an improved rivet driver in order to tackle space constraint.
3.Use of invention
This invention is to carry out riveting operation which was earlier found difficult due to space constraint.
4.Prior art
In the prior method, it was difficult to rivet the cleat rivets with the existing standard drivers due to space constraints.
5.Draw backs of prior art
Due to the difficulty experienced in the carrying out the riveting operation because of space constraint, it led to deformation of rivet head and improper rivet bulb forming. And in such cases, such improperly bucked rivets had to be de-riveted. Occasionally, this also led to the enlargement of rivet holes. This resulted in loss of productivity.
6.Comparison between prior art and present invention
In the prior method, riveting operation was carried out by standard rivet drivers while in the present method, riveting is done with the help of the customized rivet driver which enabled adequate access to the area of operation.

7.Aim of the invention
Aim of the invention was to fabricate a customized rivet driver to aid in riveting operation where there is space constraint.
8.Summary of the present invention
Due to the space constraints, there was inadequate space for the rivet drivers required for riveting the IFR light to the airframe. The customized rivet driver ensured access to the area of riveting was adequately obtained and this led to the elimination of rivet head getting deformed and also formation of improper rivet bulbs. This also ensured that de-riveting of improper rivets were avoided.
9.Brief description of drawings
FIG-1 is a perspective view of a location of IFR Light in an Aircraft.
FIG.2 illustrates the customized river driver which was fabricated.
10.Statement of invention
This invented customized rivet driver aids in riveting where it is difficult to get access for the standard rivet drivers due to space constraints.
11.Detailed description of invention
a)The In-Flight Refueling (IFR).Light is to be installed on the airframe and its function is that it is switched on whenever In-flight refueling is in progress.
b)The IFR Light is attached to the airframe with the help of rivets which are permanent fasteners. The position of the IFR Light is extremely intricate and not having adequate space for the rivet driver.
c) Previously, the standard rivet drivers were used for the riveting operation. But due to intricacy & space constraint, there was inadequate space for holding the rivet drivers as required. This led to the deformation of rivet head and
improper formation of bulb. In such circumstances, it was required to then de-rivet the improper rivets and rivet new ones.
d)In this invention, a Z-shaped rivet driver as shown in Figure 2 was fabricated
considering the space constraint. With the help of this rivet driver, it was possible to gain proper access to the area where the IFR Light is to be installed/
e)Also, it was also ensured that the problems in the prior method such as deformation of river head and improper formation of rivet bulb were avoided.
f)Also, the need for de-riveting the improperly rivets was also avoided^

Claims We claim
1.The customized rivet driver which enables the operator to have adequate access to the area of operation which was otherwise difficult.
2.Z shaped design of the customized rivet driver.
